Mercury forms an amalgam, an alloy, with gold particles to allow for the efficient capture of gold from the ore. The gold is concentrated by boiling away the mercury from the amalgam. This process is called retorting. [59] This is effective in extracting very small gold particles, but the process is hazardous due to the toxicity of mercury vapour.
There are two principal phases of underground mining: development mining and production mining. Development mining is composed of excavation almost entirely in (non-valuable) waste rock in order to gain access to the orebody.

High-grade gold ore from the Harvard Mine, Jamestown, California, a wide quartz-gold vein in California's Mother Lode. Specimen is 3.2 cm (1.3 in) wide. Various theories of ore genesis explain how the various types of mineral deposits form within Earth's crust. Ore-genesis theories vary depending on the mineral or commodity examined.
